This document contains device specific information for
the following devices:
This family offers the advantages of all PIC18 micro-
controllers - namely, high computational performance
at an economical price - with the addition of high-endur-
ance Enhanced FLASH program memory. The
PIC18FXX39 family also provides an off-the-shelf solu-
tion for simple motor control applications, allowing
users to create speed control solutions with small part
counts and short development times.
1.1
1.1.1
The integrated motor control kernel uses on-chip Pulse
Width Modulation (PWM) to provide speed control for
single phase induction motors. Through a convenient
set of Application Program Interfaces (APIs) and vari-
able frequency technology for open loop control, users
can develop applications with little or no previous expe-
rience in motor control techniques. ProMPT motor con-
trol provides modulated output over a range of 0 to
127 Hz, and has a pre-defined V/F curve that can be
reprogrammed to suit the application.

for both program memory and data EEPROM are
rated to last for many thousands of erase/write
cycles - up to 100,000 for program memory, and
1,000,000 for EEPROM. Data retention without
refresh is conservatively estimated to be greater
than 100 years at 25°C.
their own program memory spaces under internal
software control. By using a bootloader routine
located in the protected Boot Block at the top of pro-
gram memory, it becomes possible to create an
application that can update itself in the field.
module is capable of standard RS-232 operation
using the internal oscillator block, removing the
need for an external crystal (and its accompanying
power requirement) in applications that talk to the
outside world.
8 conversion channels for flexibility in sensor
monitoring and control, as well as the ability to do
conversions while the device is in SLEEP mode.

Devices in the PIC18FXX39 family are available in
28-pin (PIC18F2X39) and 40/44-pin (PIC18F4X39)
packages. Block diagrams for the two groups are
shown in Figure 1-1 and Figure 1-2.
The devices are differentiated from each other in four
